Benthos of a sublittoral sandbank in the Southern Bight of the North Sea: general considerations

OMA

Willems, K.A.; Vanosmael, C.; Claeys, D.; Vincx, M.; Heip, C.H.R..

The benthic fauna of the Kwinte Bank, a linear sandbank in the Belgian coastal waters of the North Sea, was sampled on ten stations in September 1978. This sandbank shows a linear gradient from fine sandy sediments in the south to coarser sandy sediments in the north as a result of the tidal current pattern in the region. The influence of this gradient on macro- and meiofauna was studied. Diversity of polychaetes and harpacticoid copepods is correlated with median grain size of the sand fraction, diversity of nematodes is not. The influence of station location and sediment characteristics on density of all major macrobenthic groups is very outspoken, and linear density trends are common. This is not true for meiofauna in general and nematodes and copepods...

Macrobenthos of a sublittoral sandbank in the Southern Bight of the North Sea

OMA

Vanosmael, C.; Willems, K.A.; Claeys, D.; Vincx, M.; Heip, C.H.R..

The benthic fauna of a linear sandbank, the Kwinte Bank, in the Belgian coastal waters of the North Sea was sampled on ten stations in September 1978. Density and species composition of the macrofauna and sediment characteristics have been studied. The Kwinte Bank shows a gradient from finer sediments in the south to coarser sediments in the north, resulting from the tidal current pattern in the region, and can be considered as a biogeographical island as the bank is surrounded by a region of much finer sediments. The macrofauna consists of 73 identified species and has an average density of 4910 ind./m² and an average diversity of 2.5 bits/ind. Interstitial polychaetes predominate and among those <i>Hesionura augeneri</i> is the most abundant...
